An infrared transmissive product includes a body. The body is configured to cover a transmitting unit and a receiving unit for infrared rays in an infrared sensor. The body includes a base made of a transparent plastic having an infrared transmissivity, and a coating film layer that is formed on a rear surface of the base in a transmission direction of infrared rays from the transmitting unit and has an infrared transmissivity. The coating film layer includes dispersed aggregates of particles of a pigment.

Infrared transmissive product

A vehicle sensor unit includes a millimeter wave radar device, an infrared sensor that is arranged at a position adjacent to the millimeter wave radar device, and a cover having a first cover portion and a second cover portion. The first cover portion is located in front of the millimeter wave radar device in a transmission direction of the millimeter waves to conceal the millimeter wave radar device and has millimeter wave transparency. The second cover portion is located in front of the infrared sensor in a transmission direction of the infrared light to conceal the infrared sensor and has infrared light transparency. The millimeter wave radar device and the infrared sensor are attached to the cover so that the whole vehicle sensor unit is configured as a single unit.

Vehicle sensor unit

An onboard sensor cover includes a cover body that includes front and rear bases and a decorative layer. The front base is made of a transparent plastic material that permits passage of an infrared ray and a millimeter wave and includes a rear surface in the transmission directions of the infrared ray and the millimeter wave that is configured by a first uneven surface. The rear base is made of a plastic material that permits passage of the infrared ray and the millimeter wave and includes a front surface in the transmission directions that is configured by a second uneven surface. The decorative layer is made of a material that reflects visible light and permits passage of the infrared ray and the millimeter wave and is in contact with the first and second uneven surfaces. The front and rear bases are made of the same type of plastic material.

Onboard sensor cover

There is provided a near-infrared sensor cover to be applied to a near-infrared sensor including a transmitting unit that transmits near-infrared radiation to outside of a vehicle and a receiving unit that receives near-infrared radiation reaching and reflected by an object outside the vehicle, and to cover the transmitting unit and the receiving unit. The near-infrared sensor cover includes a luster layer formed by dispersing a filler in a coating film, the filler including a core and a shell that covers the core with a material having a refractive index different from that of the core. Light transmittance of near-infrared radiation in the near-infrared sensor cover is 60% or more.

Near-infrared sensor cover

There is provided a near-infrared sensor cover to be applied to a near-infrared sensor including a transmitting unit that transmits near-infrared radiation and a receiving unit that receives near-infrared radiation reflected by an object. The near-infrared sensor cover includes a cover main body portion disposed with a thickness direction thereof to be coincide with a transmission and reception direction of the near-infrared radiation and covering the transmitting unit and the receiving unit, and a heater wire disposed on the cover main body portion to generate heat when energized. The heater wire includes plural straight line portions that extend in parallel to each other and plural connection portions that connect end portions of adjacent straight line portions. An interval between adjacent straight line portions ranges from 3 mm to 10 mm, and a diameter of the heater wire ranges from 0.01 mm to 0.2 mm.
